From VDH on The Way Our World Works (h/t, Am Digest - with Randy Newman's Short People):
...those on the left are moralists, smarter people who pass up their own personal agendas to help the community. They think of society, not self, and so when they err, they do it under stress, in accidental fashion, and with no lasting significance — not like their selfish Neanderthal cousin conservatives, for whom transgression is a valuable window into their flawed souls. Bushisms became a media pastime, but no one suggests that a president who says Cinco de Quatro, or 57 states, or references the “Austrian” language is a Dan Quayle wrestling with potato.
